The Second Avenue subway project is rattling nerves, cracking tiles, jarring gas lines — and caused a dog named Buttons to nearly lose an eye.

The unlucky pup was walking near the construction site at 96th Street and Second Avenue when a piece of jutting metal poked him in the eye.

Robin Hair got $1,669.48 from the MTA for the pooch’s medical bills, according to documents obtained by The Post.

Hair’s case was among 60 property-damage and lost-business claims submitted to the MTA since 2008 from fed-up Upper East Side business owners and residents. Most claimants are still waiting for the transit agency to make good.

Dana Renert said she’s getting the runaround on the claim she submitted in May after her shower tiles fell off the wall, the crown molding in her living room cracked, and plaster plummeted from her daughter’s bedroom ceiling.

“I keep calling and calling and calling,” she said.

Joe Pecora, owner of Delizia pizzeria and restaurant at 92nd Street and Second Avenue — near a key staging area for the project — said he is seeking about $20,000 after his power was cut twice in 2008. In another instance, patrons and workers fled the restaurant after an electrical panel exploded in the basement.

“They’re pointing fingers at each other,” he said. “Con Ed is pointing fingers at the MTA, and the MTA is pointing fingers.”

The MTA has paid out just nine claims totaling $87,489, including $231.25.

“We respond to claims and process them accordingly — predicated on whether or not plaintiffs have provided all required information,” according to an MTA spokesman.
